Description

ネジ１０は、保持部材８を貫通してネジ穴２０にねじ込まれ、一対の保持部材８を互いに近づく方向に押圧する。本実施形態においては、ベース部材９とネジ１０とで押圧部材を構成している。ネジ１０を用いて保持部材８とベース部材９とをネジ止めすると、保持部材８がビームスプリッタ５及び直角プリズム７を図１の白抜き矢印方向に挟み込んだ状態で、保持部材８がベース部９に固定される。従って、ビームスプリッタ５には、側面と平行な方向（図１〜３におけるＹＺ平面と平行な方向）の力が加わらない。この結果、ビームスプリッタ５の光学機能面１１が、剥離したり、破壊されたりすることを防止できる。 The screw 10 penetrates the holding member 8 and is screwed into the screw hole 20 and presses the pair of holding members 8 in a direction approaching each other. In the present embodiment, the base member 9 and the screw 10 constitute a pressing member. When the holding member 8 and the base member 9 are screwed together using the screws 10, the holding member 8 holds the beam splitter 5 and the right-angle prism 7 in the direction of the white arrow in FIG. Fixed to. Therefore, a force in a direction parallel to the side surface (a direction parallel to the YZ plane in FIGS. 1 to 3) is not applied to the beam splitter 5. As a result, it is possible to prevent the optical functional surface 11 of the beam splitter 5 from being peeled off or destroyed.
